Building these indexes takes forever!
Anyway -- ANYTHING we can do to make this go faster is appreciated :)
Here's some vital statistics:
- Machine is a 16 GB, 4 actual CPU dual-core opteron system using SCSI
discs. The disc configuration seems to be a good one, it's the best of all
the ones we've tested so far.
What are your shared_buffers, work_mem, and maintenance_work_mem settings?
maintenance_work_mem is used for CREATE INDEX, and with 16GB of memory in the
machine, maintenance_work_mem should be set to at least 1GB in my opinion.
shared_buffers = 8GB
work_mem = 256MB
maintenance_work_mem = 6GB
So that should be covered, unless I'm using too much memory and swapping.
It does look like it's swapping a little, but not too badly as far as I
can tell. I'm thinking of dialing back everything a bit, but I'm not
really sure what the heck to do :) It's all guessing for me right now.
